SPECIFICATION forming part of Letters Patent No. 621,307, dated March14, 1899.

Application filed June 30, 1896. Serial No. 597,637. (No model.)

To all whom it may concern.-

Be it known that I, ALONZO R. MALLORY, a citizen of the United States ofAmerica, and a resident of Atlanta, in the county of Fulton and State ofGeorgia,'have'made a certain new and useful Plow; and I do herebydeclare the following to be a full, clear, and exact descrip tion of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same, reference being had to theaccompanying drawings, and to figures of reference marked thereon, whichform a part of this specification.

In the accompanying drawings, Figure 1 is a perspective View of thedevice, showing same with wings attached. Fig. 2 is a front eleva tionof a set of blades, including heel-sweep wings. Fig. 3 is a sideelevation of the standard, showing the backing for the belts in positionthereon. Fig. 4 is a plan view of the heelplate. Fig. 5 is an edge Viewthereof. Fig. 6 is a cross-section on the line 6 6, Figs. 4. and 5. Fig.7 is aside elevation of the casing serving as a backing for the belts,showing its form and manner of attachment to the standard. Fig. 8 is arear elevation thereof, and Fig. 9 is an inverted plan view of same.Fig. 10 is a cross-section on the line 10 10, Figs. 7 and 8. Fig. 11 isa side elevation of the gage-wheel, and Fig. 12 is a rear elevationthereof. Fig. 13 is a plan of side gage-wheel attachment. Fig. 14c is aside of the clevis. Fig. 15 is a detail of the stop-plate therefor, andFig. 16 is a plan of said clevis. Fig. 17 is a side elevation of theclamp securing the pivoted standard to the beam proper. Fig. 18 is asection on the line 18 18, Fig. 17. Fig. 19 shows means for securingsaid beam and standard in adjustment. Figs. 20 and 21 are respectivelyback and sectional Views of point, forming the extreme end of the sharewhen assembled. Fig. 22 is a side view of the opener-blade. Fig. 23 is aface view of the right-hand turn-plow point.

In the figures like reference characters are uniformly employedin thedesignation of corresponding elements of construction.

1 is a beam which is composed of two fiat metallic bars curved in theform of a modified sigmoid and terminating at the back ends,substantially as shown in Fig. 3, on which point on bolt or pin 2 ispivoted to the standconsisting of straps 5 and bolts 6 serving to.'

converge the two side bars onto the forward end of the said standardwhen said beam is in the adjustment shown in Fig. 1, and when the barsare relatively situated, as seen in Fig. 19, are in exactly the reverseposition. The corresponding one of said bars 6 engages the notch 4,preventing the movement of the bars relatively to each other and at thesame time, as before stated, clamping the side bars to the beam and saidstandard securely together.

7 are the handles, which are assembled in the usual manner and aresecured by their lower ends to the beam by the pivoting-bolt 2, eitherdirectly or, as indicated in Fig. 3, by means of straps 7,which wouldthen form part of said handles.

7 S are braces which extend from the handles 7 in approximatelyhorizontal direction and are attached at their other ends to the beamjust back of the clamp hereinbefore described, bolts 9serving to securethem there, and said braces being made adj nstable as to their point offorward attachment by means of a series of wheels 10 through the braces8 and adapted to receive bolt 9.

As shown in Figs. 1, let, 15, and 16, the forward ends of bars are heldtogether by means of bolts 11, which said bolts also serve to secure theclevis 12 thereto. This clevis consists of two parallel portions 12,having a loop 12 bent at their forward ends, wherein the usual notchesare out to receive the singletree-ring, and bya movement of which ringfrom notch to notch an adjustment of the line of draft is secured. Thering is secured in the desired one of these notches by means of a plate13,which is bifurcated at its lower end and slotted in its upper end,the

cular in contour, as shown at'14 in Fig. 15.

This circular portion of the slot is necessary to allow the said plateto be slipped over one of the parallel portions 12 of the clevis and tobe turned into place and slipped between the lips 13' and the lugs 13"on the clevis, which are so situated on said clevis that the platetouches or nearly touches the dividing-lugs between the notches. Fromthis position it may be moved by drawing it upwardly, causing itsbifurcated lower end to pass from between the lips 13 and so allowingsaid lower end to swing backwardly and the ring to be passed from notchto notch. In order that the upper end of the plate 13 may not slipbackwardly also and so allow said plate to become displaced andtroublesome, I have provided the hereinbefore-mentioned lugs 13", whichare of a size to just fill the opening 11 and allow said opening to passover them, and after passing the plate over them said opening 11 isreduced in size by the blow of the hammer on the edge of the plateadjacent thereto, and said plate may not then fall backwardly at itsupper end.

Figs. 1, 11., 12, and 13 show a caster-wheel or gage-wheel which isconstructed and made vertically adjustable, as follows: A plate 15 issecured in a horizontal position centrally under the forward end of thebeam proper by means of a clip 16, as shown in Figs. 12 and 13, saidclip passing its bifurcated end through the holes in the aforesaid plateand straddling the beam-nuts, serving to draw same tight and providingfor a fore-and-aft adjustment. For the sake of stiifness of said plateand of forming suitable abutments for the contacting of parts flanges 15are made on the said plate, projecting downwardly on its fore-and-aftedges. In each edge of said plate parallel to the beam are slots, saidslots being set slightly backwardly from the center of said plates,whereby a lip 15" is lifted for engagement with the teeth 17 of thestandards 17, which teeth lie along-the front edge of each of saidstardards and engage the lips 15, the standards being from the points oftheir teeth to the back edge of a size equal to the length of theaforesaid slots, whereby they may be moved vertically through said slotsand provide for the adjustment of the casterwheel 18, carried freelyrotatable between their lowerends, the upper ends of said standardsbeing held, if desired, by a bolt 19. In order to hold these standardsin their proper vertical positions, it is necessary that the teeth 17should not only engage the lips 15", but that said engagement should bemade stable and the uprights be thereby secured against oscillation.This I do by means of a wedge-shaped key 20, which fills the slotbetween the back edge of each standard 1'7 and the correlative flange15' and is driven thereinto from the top, havinga lug bearing on theback edge of the standard and having a shackle 20 partially encirclingthe said standard above the plate 15.

To the lower end of the standard 3 is secured the base or backing, towhich are sccured, by means of suitable bolts or rivets,the blades orshare-sections, all of which I will now proceed to describe.

21 is a casting which is provided with lugs 21 on its back edge, bymeans of which and the bolts 21" said casting is secured to the foot 3.Obviously a flange or flanges may be substituted for these lugs withouta departure from the essence of the invention. The face of the casting21 is of a form shown in Figs. 3 and 7to 10, inclusive, and is inclinedbackwardly from the vertical median, so as to conform as nearly aspossible to the form of the back of the plates 22. At their inner edgesas nearly as practicable the holes 23 are made therein for suitablebolts or rivets with which to secure said plates in place. The backwardinclination of the faces of this casting is such as will give the plates22 or any plate which it is desired to ailix thereto the desiredcorrelative inclination. This is also a fact, as the degree of anglefrom the horizontal of the lower portion 24 of these faces, or ratherthe lower end of the casting 21, which will be observed in Fig. 3, is atan angle of approximately thirty degrees, whereas the angle of the mainbody is about fortylive degrees. This proportion would be ordinarilyabout correct; but I have shown in Fig. 7 a different angle of thislower portion 24, to which a long point, somewhat after the manner of asubsoiling-point, might be attached. 25 is a lug which projects upwardlyfrom said casting, for a purpose to be hereinafter treated of. The lowerend of the said casting 21 is shaped so that it will enter under the lip26 on the casting 27 011 the back side of the blade 28, which forms thepoint of the share when assembled and which is scoured to the casting 21by bolts passing through the holes 28 in the said blade and 24 in theaforesaid casting 21, the upper edge of said blade being of a formcorrelative to the lower ends of the plates 22, whereby it forms acontinuous surface therewith and is held more rigidly in place.

Fig. 22 is a detail of an opening-blade 29. (Shown in front elevation inposition in Fig. 2.) This blade conforms its back edges to the front ofthe casting 21 as far as it contacts therewith, having on its upper endan eye 29, which corresponds in position with the hole 25 in the lug 25,to which it is secured by suitable bolt or rivet lying between the inneredges of the plates 22 and in the slot 28 in the plate 28, a tang 29"projectinginto the opening 29,formed by reeessing the block 27, and sosetting said block on the point 28 as to allow a portion of said pointto close one side of the recess aforesaid. Projecting front edge of thisblade 29 may be of any desired contour and is sharpened so as to makethe initial out in the earth and cut roots or other like obstructionswith which it may contact.

It is obvious that any kind or character whatever of blades may beattached to this device and form any of the well-known forms of shareand of any size, as well as many other shapes of blades for specialwork.

As shown in Figs. 7 and 10, the under side of the casting 21, near thepoint thereof, is concaved, and a rib 30 runs down the center of saidconcave, as shown in Fig. 10. Seen in Figs. 4, 5, and 6 is a slide-bar31, which carries on its back end a heel-plate 32,0f hard material, andconforms at its front end to the shape of the portion of the casting 21just described, with the exception that it falls short of faces 30'.Slide-bar is clamped in place by means of bolts passing through theholes 24, 24, 23, and 23, a depression 31 being made in the upper sideof this bar, into which the lower end of the foot 3 and the lugs 21(lower) fit and contact with the bottom, thereby further bracing thisside plate. A depression 31 fits over a portion of the rib 30, andthereby still further secures the bar in place. In the recess justmentioned,formed between the faces 30' and the contiguous upper side ofthe bar 31, are inserted the contiguous ends of heel-sweep blades 33,which when assembled stand at relative angles,

(shown in Fig. 2,) said blades being held in place by bolts passingthrough the holes 24, 24', 23, and 23. This construction clamps theseblades firmly and provides a much betterheel-sweep than the ordinaryintegral one,
